Method for specific wet chemical treatment of flat products in continuous installations

摘要

The method concerns specific treatment of flat products (3) in the framework of wet chemical and/or electrochemical treatment, as well as rinsing in a continuous installation with nozzles, nozzle blocks or flooding nozzles. It is characterised by the following steps: a) loading of the installation with products of different thickness in an arbitrary sequence; b) determination of the dimensions of the products before the first nozzle arrangement (13); c) tracking of the position of the products from the instant at which their dimensions were determined to the end to the last treatment and rinsing section; d) adjustment of the hydrodynamic conditions of the nozzle arrangements along the transport path to the requirements of the products in each particular nozzle zone.
